About
GP-LAM is Manastu Space’s modular green propulsion Liquid Apogee Module designed for launch vehicle upper stages, orbital transfer vehicles, and GEO stationary satellites. It provides multi-restart apogee raise, precise circularization and plane change, rideshare dispersion cleanup, and compliant passivation/deorbit capability. The system includes propellant and pressurization gas tanks, feedlines, electrical connections, and sensors, with mechanical, power, data, gas, and liquid interfaces to the launcher. GP-LAM was Manastu’s first commercial contract, delivered to France-based aerospace company Latitude, functioning as an Auxiliary Propulsion System performing stage separation, orbit stabilization, and safe deorbiting. The system uses Manastu’s proprietary MS289 hydrogen peroxide-alcohol green propellant with an ultra-high-temperature ceramic catalyst operating at 1400°C.
